whether storm water discharge from any part of the MS4 contributes to a303(d) listed (i.e., impaired) waterbody.A 303(d) list of impaired water bodies isavailableat https://wq.deq.utah.gov/.
Water quality impaired waters means any segment of surface waters that has beenidentified by the Division as failing to support classified uses. If the Co-Permitteehas discharges meeting
these criteria, the Co-Permittee shall comply with Part 3.1.2.and Part 3.2., if applicable, and if nosuchdischarges exist,theremainderofthis Part 3.1doesnotapply.If the Co-Permittee
has “303(d)” discharges described above, the Co-Permittee mustalso determine whether a Total Maximum Daily Load (TMDL) has been developedby theDivision and approved by EPA forthelisted
waterbody.Ifthereisanapproved TMDL, the Permittee must comply with all requirements associated withthe TMDL (see Part 3.2.) as well as the requirements of Part 3.1.2. below.If no TMDL
has beenapproved, the Co-Permittee must comply with Part 3.1.2. below and any TMDLrequirements once it has been approved.TMDL requirements may be put into effectat anytime duringthis
Permit term.WaterQualityControlsforDischargestoImpairedWaterbodies.IftheCo-Permittee discharges to an impaired waterbody, the Co-Permittee shall include in itsSWMP document a description
of how the Co-Permittee will control the discharge ofthe pollutants of concern.This description must identify the measures and BMPs thatwillcollectivelycontrolthedischargeofthepollutantsofconcern.Themeasuresmust
be presented in the order of priority with respect to controlling the pollutants ofconcern.Where a discharge is already authorized under this Permit and is later determined tocause or

have the reasonable potential to cause or contribute to the violation of anapplicable water quality standard, the Director will notify the Co-Permittee of suchviolation(s).TheCo-Permitteeshalltakeallnecessaryactionstoensurefuturedischarges
do not cause or contribute to the violation of a water quality standard anddocument these actions as required by the Director. If violations remain or re-occur,coverage under this Permit
may be terminated by the Director and an alternativegeneral Permit or individual Permit may be issued. Compliance with this requirementdoes notpreclude any enforcementactivity as provided
by the Utah Water QualityActforthe underlyingviolation.
Jordan River Watershed Wide Escherichia coli (E. coli) TMDL
Co-Permittees that discharge to waters listed on the Utah 303(d) list as impaired for E.coli for which storm water is a contributing source per the Jordan River Watershed Wide E.coli
TMDL must update their SWMP document within 180 days to include a written plan (TMDL Compliance Plan)addressing the pollutant reduction requirements of the TMDL as it relates to MS4s.
The Jordan River E.coli TMDL MS4 Guidance Document available on the division’s website will provide supplemental information to assist MS4s in compliance with the below Permit requirements.
The TMDL Compliance Plan will supplement and build-on the six (6) minimum control measures identified in Part 4.2 of this permit. The Permittee must develop, fund, and implement source
control BMPs that reduce the discharge of E. coli. The TMDL Compliance Plan must address the following:
Identify potential sources of E. coli in the MS4 and target specific audiences that may be contributing to the E. coli sources. Provide and document education and outreach given to the
target audiences on the impacts to water quality associated with these types of discharges and BMPs that can be implemented to reduce the discharge of E. coli.
The Co-Permittee can meet the requirements of permit part 3.2.2.1. through contribution to a collaborative program (e.g., storm water coalition) that evaluates, identifies, and targets
sources, as well as, provides outreach that addresses E. coli.
The Co-Permittee must maintain a written or mapped inventory of areas in the MS4 that are potential sources of E. coli (areas with septic, dense waterfowl areas, dog parks, etc.).
The Co-Permittee must create a plan to prioritize reduction activities to address the areas and sources identified in the inventory. The plan must include BMPs the permittee will implement
over the permit term (structural and non-structural).
The Co-Permittee must add the inventoried areas to the priority areas identified in permit part 4.2.3.3.1. and begin inspecting the additional priority areas annually at a minimum and
documenting the inspections on an inspection form.
The Co-Permittee must add the inventoried areas to the priority areas identified in permit part 4.2.6.6.2. for street sweeping and storm sewer system maintenance and begin maintaining
the areas at the same frequency. The Permittee’s road and parking lot sweeping and storm drain system maintenance SOPs should identify all priority areas (including E. coli sources)
and must include a schedule that includes priority area frequency.
The Co-Permittee must evaluate their written inventory of potential “high priority” permittee owned and/or operated facilities (Permit Part 4.2.6.1.) and identify sites that have potential
sources of E. coli. Permittees must add to their inventory any Permittee owned or operated dog parks, parks with open water, sites with septic, or properties that are known potential
sources of E. coli. Sites that have been identified as potential sources of E. coli must have BMPs (structural or nonstructural) that reduce the potential of the discharge of E. coli.
The Co-Permittee must evaluate the potential E. coli generating activities below to determine whether existing SOPs should target reduction of E. coli discharge or if additional SOPs
should be developed for the reduction of E. coli discharge from the MS4:
Roads, highways, and parking lots: Surface cleaning and controlling litter
Parks and open space: Lake and lagoon maintenance
Parks and open space: Mowing/Trimming/Planting
Storm water collection and conveyance system: Inspection and Cleaning of Stormwater Conveyance Structures, Controlling Illicit Connections and Discharges, Controlling Illegal Dumping

Material storage areas: Solid Waste Collection, Controlling Litter, Controlling Illegal Dumping
Storm water collection and conveyance system: Water line Maintenance, Sanitary Sewer Maintenance, Spill/Leak/Overflow Control, Response, and Containment.
The Co-Permittee must promote the use of Low Impact Development (LID) controls for which E. coli (listed a bacteria) has a medium or high pollutant removal effectiveness, as identified
in the Guide to Low Impact Development within Utah, Appendix C on the division’s website: https://documents.deq.utah.gov/water-quality/stormwater/updes/DWQ-2019-000161.pdf.
The Co-Permittee must add potential E. coli reduction as a criterion for ranking when evaluating the Permittees retrofit plan (Permit Part 4.2.6.9.).
The Co-Permittee must report annually on their TMDL compliance by submitting the TMDL Compliance Report section within the annual report form on the Division’s website. The first TMDL
Compliance Report within the annual report will be due to the Division by October 1, 2024.The reporting will include identification of problem areas for which source control BMPs were
developed, the cost, and the anticipated pollutant reduction. NitrogenandPhosphorusReduction
As part of the Co-Permittee's Storm Water Management Program (SWMP), all Co- Permittee’s must specifically address the reduction of water quality impacts associated with nitrogen and
phosphorus in discharges from the MS4.
The Co-Permittee can meet the requirements of this section through contribution to a collaborative program (e.g., storm water coalitions) to evaluate, identify, target, and provide outreach
that addresses sources within the Co-Permittee’s watershed.
The Co-Permittee must determine and target sources (e.g., residential, industrial, agricultural, or commercial) that are contributing to, or have the potential to contribute, nitrogen
and phosphorus to the waters receiving the discharge authorized under this Permit.
The Co-Permittee shall prioritize which targeted sources are likely to obtain a reduction in nitrogen and phosphorus discharges through education. The Co-Permittee must distribute educational
materials or equivalent outreach to the prioritized targeted sources. Educational materials or equivalent outreach must describe storm water quality impacts associated with nitrogen
and phosphorus in storm water runoff and illicit discharges, the behaviors of concern, and actions that the target source can take to reduce nitrogen and phosphorus. The Co-Permittee
may incorporate the education and outreach to meet this requirement into the education and outreach strategies provided in accordance with Permit Part 4.2.1.4.0StormWaterManagementProgram

all projects subject to the requirements in 4.2.5.1.2. A LID approach promotes theimplementationofBMPsthatallowstormwatertoinfiltrate,evapotranspireorharvest and use storm water on site
to reduce runoff from the site and protect waterquality.
Guidance for implementing LID can be found in DWQ’s LID controls which areappropriate for use in the State of Utah can be found in A Guide to Low ImpactDevelopment within Utah(the Guide),availableon
DWQ’swebsite.
Co-Permittees must allow for use of a minimum of five LID practices from the list inAppendix C of the Guide. If a Co-Permittee has not adopted specific LID practicesfrom Appendix C,
any LID approach that meets 4.2.5.1.2 and is feasible may be usedtomeetthisrequirement.Since 2010, rainwater harvesting is legal in the State of Utah. Depending on thevolume of rainwater
collected and stored for beneficial use, the Co-Permittee mustmeet the requirements of the Utah Division of Water Rights to harvest rainwaterfoundontheir website:http://waterrights.utah.gov/forms/rainwater.asp.Feasibility.
